Embodiment 1

[0019] Weigh 95.8g of 500CS simethicone oil, 4g of polyaryl silicone resin, 0.2g of modified triethylenediamine, 10g of No. 120 mineral spirits, put them into the experiment emulsification reaction kettle and stir evenly, then put into the ratio NP-10:OP -10: TX-10: Tween 80 is 1:2:0.5:0.8 3g of compound emulsifier mixed evenly; weigh 387g of deionized water into the kettle, and at the same time quickly raise the temperature to 50°C, constant temperature reaction for 6 hours and it will be effective Milky white stock solution with 20% solid content.

[0020] Weigh 10g of the stock solution and add it to 90g of alcohol to obtain an alcohol dilution with an effective solid content of 2%. Use this diluent to spray on the shoe sole mold whose mold temperature is higher than 40°C. Instead of blowing the mold with compressed air, directly pour polyurethane raw materials into it to obtain high-quality polyurethane shoe sole products with no surface hydrolysis.

Abstract

The invention discloses an alcohol-resistant blow-free aqueous mold release agent, and a preparation method and an application thereof. The preparation method comprises the following steps: adding 1-70% of a mold release effective component, 0.1-30% of an emulsifier, 0.1-30% of a bridging agent and deionized water into an emulsifying reaction kettle, and carrying out a constant temperature reaction at 40-70DEG C for 5-9h to obtain the alcohol-resistant blow-free aqueous mold release agent. The alcohol-resistant blow-free aqueous mold release agent is diluted by volatile organic alcohol to obtain a dispersion with the solid content of 0.5-3%, and the dispersion is used for mold release of a polyurethane product. In the invention, the fast volatilization of the organic alcohol is used, continuous heating is not needed by a mold in the production process, and a compressed air blowing process link is omitted, so the problems of high energy consumption and large noise are solved.

Description

technical field [0001] The invention relates to a mold release agent, in particular to an alcohol-resistant and water-resistant mold release agent and its preparation method and application. Background technique [0002] Currently known water-based release agents need to use a large amount of water to dilute the original solution to a water dilution with an effective solid content of 0.5%-3% before use. Therefore, the mold needs to be continuously heated during the production of polyurethane products. The heating power is between About 50 kilowatts per hour, and after the mold is sprayed, compressed air is needed to dry the water sprayed in the cavity, and the power consumption of the air compressor is also more than 30 kilowatts per hour, so there is a large energy consumption in the production process , The noise generated during blow molding is very high, which is not conducive to the requirements of energy conservation and environmental protection. The existing water-bas...
